One problem I have at work is that there is no WiFi signal I can use to access the main features on my N800 (like using it as a Skype Phone). I've tried to dabble with the PC-Connectivity manager to see if I can use my Laptop (connected online via eithernet) as a router for my N800 but nothing seems to work. Is there a manual somewhere I can use to have my N800 connect to the internet via my laptop when a WiFi signal doesn't exist?

Note:
I run a modified Ubuntu install on my work laptop.
